nginx is too strict about accept-ranges

I am using nginx to proxy/cache requests from different origin servers, some
of which I don't have access to (can't change their behaviour). Recently I
stumbled upon a problem where nginx wouldn't serve partial objects (even
after they are cached) although upstream server would happily do that. It
happens because upstream server doesn't serve "Accept-Ranges: bytes"
RFC7233 states that use of this header is optional so nginx might be relying
on it a bit too heavily.

Is there a configuration knob to make nginx ignore absence of this header
(or force nginx to allow ranges)? Or a patch available to apply? If not -
are there any plans to add one?
